To check a car's mileage, compare the odometer reading against the mileage recorded on service records, inspection reports and the vehicle title, and watch for physical wear that doesn't match a low reading. Look for 'Not Actual Miles' or 'Exceeds Mechanical Limits' brands on the title. NHTSA estimates over 450,000 vehicles are sold each year with false odometer readings, so verifying mileage protects you from paying too much.

Warning Signs of Odometer Fraud

  • Worn pedals, steering wheel or seats that don't match a low reading

  • Decode the VIN to confirm the exact vehicle

  • Check the title for 'Not Actual' or 'Exceeds Mechanical Limits' brands
  • Have a mechanic assess whether wear matches the claimed mileage
